The following MPlayer command successfully displays the video but does not play the audio: mplayer -tv driver=v4l2:norm=PAL:device=/dev/video2:width=720:height=576 \ c:a aac -video_size 720x576 -pixel_format uyvy422 -i /dev/video2 out.mp4 The following ffmpeg command successfully records video, but records severely distorted, broken and out-of-sync audio: ffmpeg -y -f rawvideo -f alsa -thread_queue_size 2048 -ar 48000 -i hw:0 \ The PulseAudio listing for the device is as follows: $ pactl list cards shortĠ alsa_card.pci-0000_00_1f.3 module-alsa-card.cġ4 alsa_b-Pinnacle_Systems_GmbH_DVC100-01 module-alsa-card.c ThinkPad Console Audio Control at EC reg 0x30, fw N2LHT33W Pinnacle Systems GmbH DVC100 at usb-0000:00:14.0-4, high speedĢ9 : ThinkPad EC - ThinkPad Console Audio Control The sound cards listing shows it as "DVC100": $ cat /proc/asound/cards The device is "Pinnacle Dazzle DVC 90/100/101" (as returned by v4l2-ctl -list-devices). I have tried to get ffmpeg to record the audio and I have tried to get MPlayer to play the audio and my efforts have not been successful. I am able also to see that audio is being delivered from the device to the computer by looking at Input tab of the Sound Preferences window or by recording the audio using Audacity, however the audio gets delivered from the device apparently only when the video is being accessed using ffmpeg or MPlayer. I am able to record video from the device using ffmpeg and I am able to see video from the device using MPlayer. I want to record both the video and audio from the device to a video file that has dimensions 720x576 and video codec H.264 and good audio quality.
I have a USB audio-video capture device, something used to digitize video cassettes.
